My times look very similar as well. I did 2 cycles of HPMass, so 12 weeks so far and now in the 1st week of my 3rd cycle. The first 2 cycles I wasn't able to incorporate lower pushing after my upper pushing days and vice versa just so I would have enough time to spend with the family.
I also didn't have time to do the eccentric-less work as prescribed for the lower pushing as I didn't have access to a sled or prowler. So that helped keep my time down, however I just had a prowler style sled built so I'm curious to see how that takes up my time, I'm thinking maybe an extra 30 mins but that's not much in reality.
But 2 hours is the average for me, less during the first week and longer as week 2 and 3 come up. The thing with this program is I feel like it's providing good volume even if you leave out the extra pushing work and eccentric-less work - of course results aren't as good but I like it as is.
This 3rd cycle will have me nearly fully equipped to do all the exercises, buying a prowler style sled really excites me this 3rd cycle around. The only thing I'm still missing is a lat machine, right now I use a dangerous setup of my BB and "blast straps", it works like a lat machine but isn't for the faint of heart.
Just do what you can in the time you have, just be sure to get all the workouts in and you should be getting results like I did. Visibly thicker all around and my MTW's have been increasing nicely.
